Water Management • 6 Licenced Discharge Points (LDPs): – Require frequent inspections & sampling during discharge; – Submitted application to EPA September 2013 to add 3 new LDPs to EPL 528;  Charbon required to undertake additional water quality monitoring & submit to EPA;  November 2014 received a revised EPL with 3 additional LDPs. • Since last CCC meeting (15/09/2014 – 09/03/2015) ≈ 450 mm rainfall • [Long-term annual average ≈ 684 mm – from BoM station at Rylstone; LDP002 LDP003 LDP004 LDP005 LDP006 Discharges: 5 6 1 30 1 Exceedances: 0 2 0 2 0 • 4 Exceedances of EPL528 for TSS & Turbidity from LDP003 & LDP005. Exceedances covered by Condition L2.5 of EPL528; all other conditions were below license limits. 3

Environmental Management • Monitoring: data for dust has shown that the mine has been in compliance consistently for > 12 months:  HVAS 2014 – 2015 (to date): *Compliant.  Depositional Dust 2014: *Compliant  2x depositional dust exceedances (Feb & Apr) due to contamination by organic matter;  1x depositional dust exceedance (May) due to contamination – deemed to be non- mining related. In any case, location where DDG located is on property with whom Charbon holds a negotiated agreement which removes limits including dust.  All 2015 results to date have been in compliance. • Dust PRP: *Now Complete  Condition U3 Report Submitted to EPA on 14 April 2014;  Comments received from EPA on 13 June 2014; a report addressing these was submitted on 30 July 2014;  Condition U1 & U2 Reports Submitted to EPA on 15 August 2014. 11

Environmental Management • Noise Management: – Quarterly noise monitoring conducted during December 2014, March 2015 showed the mine to be in compliance; – Minimal operation occuring onsite during December 2014 monitoring. – Implemented new noise mitigation strategy for the Southern and Western Outlier mining areas. • Reduced Equipment Fleet, Operations dictated by weather conditions. – 2 x Noise complaints received on the 17 th and 18 th February 2015. EPA monitored at affected residence and results were below the noise criteria of 35dB. Charbon was compliant with 2010 Consent Conditions and as such no further action was required. Charbon will continue to adopt the noise mitigation strategies to maintain compliance and best practice. 14

Environmental Management • Reporting to Corporate, State & Federal Governments: – Website data uploaded within 14 days of start of month; – Dust PRP Reports to satisfy Conditions U1, U2 and U3 of EPL 528, submitted to EPA; – AEMR due 31 st March 2015. – MOP/Closure Plan due 29 th May 2015 (DRE). – Consent modification underway (DPE). 15

Environmental Management • Subsidence management – on-going; • Land management, including: – Seeding of Southern Open-cut rehabilitation - October 2014; – Weed Spraying (2015 - extensive program) • Review of Site Management Plans, on-going; • EPBC Approval Conditions – on-site Compensatory Habitat; – Positive Covenant placed over on-site Compensatory Habitat Areas; – Gifting process to NSW NPWS as a SCA *Finalised Dec 2014; 16

Rehabilitation • Planned 2015 Rehab – Blue; • Western outlier has had bulk refilling of mine void with overburden; • Requires further shaping and cover with clay and top-soil; 17
